UNITE J y f "Rforncnniurf i Applicati'onfleq Julie 14,1922. serial No. '568,213kv ofwhichthe followingis a specification. t

=fThislinvention'relates to stationary rope` clamping devices and'inore particularly tof al novel and improved construction wherein the strands of the rope may be'secured 'with facilityla'nd'ease Aancbnfithout undue labor.

Theprimary object ofmy-"inventionis toVA provide* 'a novel and improved stationary rope *clampingfdevice wherein a 'swing-"v ing 'clamping'arm is'disposed v*in relation strands ofjthe"rope"in Vadditionl to locking said lever arm'when thesaine is brought into proximity 'with'th'e said standard.

Another andi equallyl important object ofv my invention is the provision 4of a stationary clamping devicefo'fthe character above specified wherein they stationary' standard and movable clamping arm'` are each provided.

with grooves toreceivey the strands' ofla'rope, said stationary standard being provided with a pulley at vits upper end whichl cooperates =with a second'pulleybelow the base of the standard to guide the rope when the same is unclamped? and when it is beingmovedt'rom one position to another upon raising or" lowering an object such as a stage curtain for instance.

A continued object of my invention is lthe provision of a stationary clamping device which is extremely simple vin construction,l consisting of a minimum number of parts, easily assembled, highly eiiicient in operation and use, strong, durable, capable of different uses and otherwise adapted to be manufac# tured at an extremely low cost whereby its commercial possibilities are greatly enhanced.

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construct-ion or otherwise altering the arrangement ot the correlated parts without departing from the spirit oi the invention or the scope of the appended claims.

Having thus described my invention what I claim as new anddesire to secure by United States Letters Patent As:-

1. A stationary clamping device oi' the class described comprising a base having a vertical standard. a clamping arm pivotally mounted on the base and movable with respect to the standard, means disposed on the inner faces of the standard and clamping arm for crimping a rope and a retaining element for said arm and standard.

2. A stationary clamping device of kthe class described comprising a base having a vertical, tapered standard, a tapered clamping arm pivotally mounted on the base and movable with respect to the standard, spaced means formed on the opposing faces of the standard and clampingarm for-crimping a rope and al slidable retaining elementfor said arm and standard. i p

3. A stationary clamping device of the class described comprising a base and a vertical standard formed therewith, said standard having a groove on its inner face, a clamping arm pivotaliy mounted on the base and movable toward the standard, said arm having a groove on its inner face and a bell shaped retaining element slidable on the standard and clamping arm for retaining the latter when clamping a rope.

4. A stationary clamping device of the class described comprising a base having a standard, a clamping arm pivoted to the base and movable toward the standard, grooves formed on the opposed inner faces of the standard and arm, said grooves being provided with' crimping beads thereon for gripping a rope and a slidable retaining ele- Iment on the standard for securing the upper end of the clamping arm.

5. A stationary clamping device of the class described comprising a base having a standard, a pulley mounted onthe standard, a tapered arm pivoted on the base and mov-V able toward the standard, grooves formed on the standard and arm for receivinga rope trained over the pulley, beads within `the said grooves for crimping a rope when the arm is moved toward the standard, and a releasable retaining element slidable on the standard and rarm for securing the same in i i its clamping position.

6. A stationary clamping device of the class described comprising abase, a grooved standard rising Jfrom the base, a grooved,

clamping arm pivoted to the base and means for retaining said arm in its clamping posiing element connected to` the base and movable ,with respect to the standard and means for retaining said standard and member in clamping position. A-

In testimony whereof I affix my signature.
